Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the vertical view of the utility model during not with steel plate.
The specific embodiment
The utility model provides a kind of hydraulic pressure push-in type bending roll machine of the U of being used for type plate; Be used for the U type bending of steel plate 6,, comprise a base plate 1 like Fig. 1, shown in Figure 2; Said base plate 1 one ends are provided with fixed frame 2, are provided with down locating piece (meaning not shown in the figures) in the said following fixed frame 2.
Be provided with four perpendicular pressure rollers 21 in the locating piece under said, 21 of said pressure rollers are provided with the gap.Four pressure roller 21 per two formation, one rows; Be respectively import department's pressure roller 211 and exit pressure roller 212; Said import department pressure roller 211 is coaxial with the center line of exit pressure roller 212; For the ease of the steel plate bending, reduce the stressed of pressure roller 21, said exit presses 212 roller spacings less than said import department pressure roller 211 spacings.
The top of said pressure roller 21 is arranged with locating piece 23; The said locating piece 23 of going up is arranged in the fixed frame 22; Said upper and lower locating piece respectively is provided with two, and said upper and lower locating piece respectively and be provided with the adjusting screw mandrel 24 that is used to regulate two locating piece spacings between upper and lower fixed frame.
The other end of said base plate 1 is provided with a hydraulic cylinder 31; Be set with a top board 33 on the plunger 32 of said hydraulic cylinder 31; Being connected with one on the said top board 33 is used for steel plate 6 pushed and pushes plate 4 between the pressure roller 21; In order to make steel plate 6 can form the U type, the said gap that pushes the thickness of plate 4 less than 21 of said pressure rollers, plunger 32 can drive and push plate 4 and move back and forth 21 of pressure rollers.
Owing to when pushing steel plate 6, need bigger power, said base plate 1 is provided with auxiliary stiffener 3, and said auxiliary stiffener 3 is arranged on the rear end of hydraulic cylinder 31.
For steel plate 6 is got in the pressure roller 21 more easily, simultaneously, reduce the misalignment of U template when advancing.Said base plate 1 is provided with the support regulating block; One side of said support regulating block and following fixed frame 2 against; Said support regulating block center offers a central channel (meaning not shown in the figures); Said support regulating block is made up of a fixed head 5 and the regulating block 51 that is arranged on two scalable spacings between the fixed head 5, forms a central channel between the said regulating block 51.The center line of said central channel and four pressure rollers 21 is coaxial, saidly pushes plate 4 passes pressure roller 21 in central channel gap and moves reciprocatingly.
Set forth the concrete method for using of the utility model down below.
At first, for the ease of the centering of follow-up steel plate, mark the symmetrical bending line of steel plate 6 in advance; Stressed deflection when preventing that hydraulic cylinder 31 from advancing is rolled curved back U shaped steel plate misalignment, and the center that adjustment pushes plate 4 overlaps with the center of four pressure rollers 21, makes hydraulic cylinder 31, pushes plate 4, roll station pressure roller 21 is centered close on the straight line.
Then; According to the specification of U type plate, adjust the adjusting screw mandrel 24 of bending roll machine upper and lower part, make the U shaped steel plate of the suitable bending of center distance of four rollers; Roll curved porch pressure roller 211 spacings during adjustment greater than exit pressure roller 212 spacings (form " import of < " type); Be adjusted to desired spacing, it is stressed to reduce roller, is convenient to the steel plate bending.
Then; The steel plate that marks bending line 6 is put in the centre that hydraulic pressure pushes part (hydraulic cylinder 31 with push plate 4) and roll station (pressure roller 21 formation roll stations); With the steel plate bending line with after pushing the coincidence of plate 4 centers; Slowly start hydraulic cylinder 31 and make and push plate 4 and promote the bending steel plates and hold out against porch nip roll 211, hydraulic cylinder 31 is reinforcing steadily, and steel plate 6 is at the uniform velocity got in four rollers.
At last, steel plate 6 roll curved after, push plate 4 and withdraw from slowly and roll curved zone.
